About CRDF
Cardiff Oncology, Inc. is a clinical-stage biotechnology company. It is leveraging PLK1 inhibition, a well-validated oncology drug target, to develop novel therapies across a range of cancers with unmet medical need. It is focused on clinical programs in indications, such as RAS-mutated metastatic colorectal cancer (mCRC), and in investigator-initiated trials in metastatic pancreatic ductal adenocarcinoma (mPDAC), small cell lung cancer (SCLC), and triple negative breast cancer (TNBC). Its lead drug candidate, Onvansertib, is an oral, small-molecule drug candidate that is highly specific for PLK1 inhibition with a 24-hour half-life. It has other ongoing and planned clinical trials of onvansertib: one trial (CRDF-004) in first-line treatment in patients with RAS-mutated mCRC, and investigator-initiated trials in first-line mPDAC, relapsed SCLC and unresectable locally advanced or metastatic TNBC.

Cardiff Oncology Management Shakeup and Trial Update
- Management Changes: Cardiff Oncology announced the resignation of CEO Mark Erlander and CFO James Levine, with board member Mani Mohindru appointed as interim CEO, reflecting a focus on execution and clinical advancement that may impact investor confidence negatively.
- Clinical Trial Data Update: In the CRDF-004 Phase 2 trial for RAS-mutated metastatic colorectal cancer, the 30 mg dose group achieved a confirmed objective response rate of 72.2%, significantly higher than the 43.2% in the standard care group, indicating the potential efficacy of the new drug and possibly driving future registrational trials.
- Registrational Trial Plans: Based on clinical data, Cardiff Oncology plans to initiate a registrational trial later this year comparing onvansertib with standard care for 1L patients, which, if successful, could help expand market share.
- Analyst Perspective: William Blair lowered the probability of success from 50% to 45%, suggesting that the abrupt management changes and narrow focus on onvansertib may limit market opportunities, leading to a 31.9% drop in stock price to $2, close to the 52-week low.
